...Otherwise, use low-level interface {View,Write}Graph * lib/Analysis/CFGPrinter.cpp - View the graph, defines passes for viewing/printing * lib/CodeGen/SelectionDAG/SelectionDAGPrinter.cpp * lib/CodeGen/ScheduleDAGPrinter.cpp - View the graph, no associate pass * lib/CodeGen/EdgeBundles.cpp - MachineFunction pass. Provide a member function to view the graph using a custom ViewGraph function because the default implementation "it won't work" * lib/CodeGen/MachineFunction.cpp - Provide member function to see/print the MachineFunction as a...
